Curucu, Beast of the Amazon

Plantation owner Rock Dean (Bromfield) travels up the Amazon River to investigate why the workers have left in panic. Dean's guide, Tupanico (Payne) warns him of Curucu, a birdlike monster who is said to live up the river where no white man has ever been. Accompanying him is Dr. Andrea Romar ([Garland), in search of a drug which (in this story) the natives use to shrink heads. She hopes this drug will be effective in reducing cancerous tissue.
